NUMBERING-MACHINE.

SPECIFICATION ierming part of Letters Patent No. 326,663, dated September 22, 188:3.

Application filed May 19, 1884. (No model.)

To all whom it may concern:

Be it known that I, JOHN W. Macaron- LAN, of Brooklyn, in the county of Kings and State of New York,have invented an Improvement in Numberirig-Machines, of which the following is a specification.

Numberingmachines have been made with number-wheels and with two ratchet-wheels arranged in such a manner that the numbers themselves are not turned each up-and-down movement of the head carrying the numberwheels; hence two or three impressions can be made of each number before the wheels are turned to the next number; but when the ma- 1 chine is to be used for printing the numbers consecutively the change cannot easily be made.

One part of my invention relates to the combination, with the number-wheels and the ratchet-wheels, of a compound pawl, the parts of which are changeable in position, so as to operate the two ratchet-wheels or only the one, and thereby make either several impressions'of one number or only one impression of each number.

In numbering-machines, especially where a thick book is being numbered, the ink-distributing table is necessarily too close to the impression-plate. I combine with the inkingtableaswing-arni andspring and adjustingand rotating devices, so that the ink-table is in an elevated position when the printing takes place, and the same yields to the inking-roller and is revolved as the roller moves across the 3 5 plate, thereby distributing the ink more thoroughly.

1n the drawings, Figure 1 is an elevation of the machine. Fig. 2 is a side View with the table in section. Fig. 3 is a rear view of the 0 number-wheels and inking-roller. Fig. 4 is a side view of such wheels with the head in section. Fig. 5 is a side view, and Fig. 6 is a rear view,of the compound pawl and carryingarm. Fig. 7 is a plan of the ink-table. Fig.

8 is a side view of the same and of its actuating parts. Fig. 9 is a front elevation of the forked head, stock, and swinging bow, and Fig. 10 is a plan of the same.

The movable table A, the frames B B, the

treadle O, pivoted at c, the connectingrod D,

and lever c are similar to the devices heretofore employed. The vertical carrierf is supported by and slides in the boxes 9 at the end of the standard H, and at h is a screw-stop, that arrests the movement of the lever e as it moves the carrier down and impresses the number upon the paper or page that rests upon the impression-plate k, and at i there is an adjustable arm,that serves as an index in placing the paper to receive the impression, and at Z is the band that passes over the impression-plate to receive any offset from the printing. These parts are represented in order to illustrate the manner in which my improve ments are employed. 6 5

At the lower end of the carrierf there is a forked head, a, through the forks of which passes the pin 2, that forms the axis of the number-disks m, which are of ordinary construction.

The inking-roller 0 has heretofore been hu ug in a swinging how, 0, that is pivoted at its upper end to the head a; but in practice it is difficult to regulate the pressure of the inking-roller upon the number-types. To obviate this I connect the pivots3 of the swinging bow 0 to a stock, 0 instead of pivoting the same to the head a, and I slot the stock and attach the same to the head by means of screws 4 4,passing through such slots into the head, so that the stock, pivots, swinging bow, and rollers can be raised or lowered, so that the ink-roller will act properly upon the nu mber-types. The bow 0 is swung by the link 1), so as to throw the ink-roller back as the head and types are carried down, and the reverse; and I employ an ink-table, Q, for inking the roller 0 and spreading the ink for the same. This table Q is upon an am, (i, that is pivoted to the standard 7, and there is a 0 spring, q, that lifts the table, and a screwstop, 8, upon the arm 6 limits the distance to which the table can be lifted. The ink-roller depresses this table as it rolls across it; but the spring q maintains contact of the roller with the ink-surface while the roller is moving back and forth upon it, and the adjustment of the screw 8 is such that the inkingroller comes into contact with the surface of the table at the front edge; hence the table is kept by the spring as high up as possible out of the way of the sheet or book that is being printed. The table has a central axis upon the under side and a ratchet-wheel, 10, and the slide 11 and spring-pawl are employed to rotate the same progressively. The bent lever 12 and link 13 to the lever 6 give motion to this slide 11 to turn the table as the head and number-wheels are being raised up; hence the ink-roller is at that time being moved by the bow 0 as its fulcrum is carried up with the number-head a. The spring-pawl '1' serves to hold the ink-table from turning back.

In numbering-machines the number-disks have been revolved progressively by apawl, 8, upon an arm, t, extending out from the aXis 2,and acted upon at the outer end by a slotted link, a, hanging from the lower arm of the standard H, so as to turn the disks one number each reciprocation of the head, the end of the pawl acting upon the ratchet-wheel v, and in some instances a second ratchet-wheel, w, has been used, having every other tooth deep or every third tooth deep, so that this wheel w will be rotated one tooth each impression; but the ratchet-wheel v and nu mber-wheels will be turned only when the pawl 8 passes into the deep notches so as to reach to and act against the teeth of the wheel 1;. In this case a single pawl is made use of that has an end that is broad enough to act upon the teeth of both ratchet-wheels, and the machine has to be adapted only to printing one number two or three times before being changed to the next number.

I make use of a compound pawl. made in the two parts 15 and 16,that swing upon the same pivot 17, and are acted upon by the one spring 18, and they are connected together by a screw or pin, 19, and there are two holes in the part 16 of the compound pawl for such screw 19, and these are placed so that when the screw is in one hole the end of the pawl that takes the ratchct-teeth is straight, or nearly so, and acts upon both the ratchet-wheels '0 w to turn the same, as before described, and move the numberavheels every second or third iinpression; but when the screw is changed so that it enters the second hole, 20, in the pawl 16, the edge of the pawl 15 will be moved back to the position indicated by dotted lines in Fig. 5, and the end of such pawl 15 will be too far back to be acted upon by the teeth of the wheel to, and hence the end of 16 will act each time upon the teeth of the ratchet-wheel v and turn the number-wheel each impression.

By this improvement the machine is adapted to the printing of numbers consecutively, or by the change in the screw of the compound pawl it is made to give more than one impression of each number as the number-wheel is turned.

I claim as my invention- 1. The combination, with the numberingwheels and the head a, that carries the same, of the inking-roller 0, the bow 0, forked at its upper end, the stock 0 passing across the head a, to which the bow is pivoted at s, and the screws at, passing through slots in the stock 0 into the head a, so as to sustain and adjust the ink-roller in relation to the numberwheels, substantially as set forth.

2. The combination, with the numberwheels, the reciprocating head carrying the same, the inking-roller,and its swinging bow, of the inking-table having a central pivot,an arm, 6, supporting the same and pivoted to the standard 7, the adjusting-screw S and spring q, and the slide-pawl l1, bent lever 12, and link 13 to the lever e, substantially as set torth.

3. The combination, wheels and the two ratchet-wheels l) '20, of a compound pawl and a screw or pin for holding the two ends of the compound pawl in the relative positions specified, for the purposes set forth.
